Hi *,
after managing to (live-)upgrade to SXCE 112 I'm running 2
"bash-3.2$ lzma -c /export/incoming/sol-nv-b112-x86-dvd.iso > /dev/null"
and transmission with enough torrents to fill up my 12Mbit/s
downstream (and enough to cause 400 to 2000 interrupts in 5 seconds
according to powertop) while checking the local data of a finished,
several gigabyte big torrent -
"load averages: 3.26, 2.79, 1.66; " (from top) and the CPU temp
slowly climbed up to 76°C and now stays there.
One interesting bit: making sure there is no network traffic kept the
CPU temp low enough to avoid a shutdown because the CPU reached 99°C
and enabled me to run live upgrade without monitoring the temp and
pausing it with ctrl+z when the CPU reached 90something °C.
I really think there's something amiss with this specific computer,
perhaps a clogged heatsink, defective fan, or poor heatsink
installation at the factory.

Oh, and I'm running a XVM/Xen-kernel which doesn't use any frequency
scaling according to powertop.

Hi *,
because of a hardware failure I'm currently using a T60p (Core Duo,
32bit) instead of a R61 (Core 2 Duo, 64bit). I simply put the HDD of the
R61 with a SXCE 110 installation into the T60p and the only obvious
'problems' are the changed network interfaces.
In scenarios with longer periods of higher load (lzma compression of
bigger logfiles, live upgrade to 111, recompiling/building the
system-set (including gcc) of my /opt/gentoo) the laptop crashes without
a dump, freeze and a few seconda later a reboot.
With console=ttya, a second laptop and dockingstations (hint: serial
port is disabled in the default BIOS settings) I found out that the CPU
reached 99°C and thus the system is rebooted.
I used this T60p before (before I got my hands on a 64bit machine) and
this problem did not occur.
My guess is there's a profile for the cpu-fan which is for the R61 (on
which the system was installed) but does not match the thermal design of
a T60p but it's still active.
Right now cpu is clocked to the max frequency but the system is idling
and 'cpupm' is enabled by /etc/power.conf:
bash-3.2$ LC_ALL=C uptime
9:49am up 33 min(s), 1 user, load average: 0.08, 0.11, 0.10
bash-3.2$ kstat -p cpu_info:::current_clock_Hz
cpu_info:0:cpu_info0:current_clock_Hz 2000000000
cpu_info:1:cpu_info1:current_clock_Hz 2000000000
bash-3.2$ cat /etc/power.conf

Main Menu -> Preferences -> Powermanagment:
Tab 'On AC Power', 'Computer speed policy' is set to "Based on processor

I cannot find anything else about controlling the fan behavior, any
hints someone?
